Gaucher disease (GD) is one of the most common lysosomal storage disorders and is caused by an inherited deficiency in glucocerebrosidase. Resveratrol is a phytoalexin that has many beneficial activities, including anti-oxidant, anti-apoptotic, and neuroprotective effects. The aim of this study was to determine if resveratrol has a therapeutic effect on primary fibroblast cells derived from a patient with type II GD. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays were performed to determine the effect of resveratrol on cell viability. The expression patterns of apoptosis-inducing factor (AIF), Bcl-2-associated X protein (Bax), caspase-3, acetyl-coenzyme A acetyltransferase 1 (ACAT1), E3-binding protein (E3BP), and citrate synthase (CS) were evaluated by Western blotting to characterize the effect of resveratrol treatment on GD cells. TLC was performed to determine glucosylceramide levels in resveratrol-treated GD cells. Resveratrol increased GD cell viability compared to untreated control cells. Further, resveratrol treatment dose-dependently decreased the apoptotic factors AIF, Bax, and cleaved caspase-3 levels, whereas ACAT1, E3BP, and CS expression dose-dependently increased. TLC analysis showed reduced levels of intracellular glucosylceramides in resveratrol-treated GD cells. These findings demonstrate that resveratrol can reduce cellular stress resulting from glucosylceramide accumulation, and suggest that resveratrol should be studied further as a novel therapeutic agent for GD.
